METHOD FOR CONTROLLING THE PRECIPITATION OF ALUMINA
摘要
<p>A method for controlling the precipitation of alumina from a Bayer process solution, the method comprising the steps of: contacting the Bayer process solution with a solid support comprising an extractant, wherein the solid support is substantially water insoluble; removing sodium ions from the Bayer process solution; reducing the concentration of hydroxide ions in the Bayer process solution; and precipitating alumina in the Bayer process solution.</p>
